WASHINGTON (Sinclair Broadcast Group) -- Dean McDermott admitted to DailyMailTV that he is behind on alimony payments but he also believes his ex-wife Mary Jo is trying to get revenge on him.

"I have taken this for years and this is the first time I've talked to anybody but I've had it," McDermott told the show. "This is a woman who is trying to exact revenge. She's constantly in the press, calling me a deadbeat dad and saying these charges are for delinquent child support. They are not."

"I got behind on it but I will pay. I told her upfront I was having a hard time financially. I reached out to Mary Jo to discuss it and work it out. Instead of being a normal human being and working it out with me, she went to courts and put me on notice," McDermott said.
